Load Linking is currently limited primarily to steel and wood framing systems because those framing systems are typically well represented by transferring the vertical support reactions from one member to another. Concrete and masonry framing can behave quite differently. Depending on the framing and detailing, the forces transferred between members may involve more than a vertical reaction. Effects such as frame continuity, fixity, torsion, bearing, and reinforcement detailing can all influence the design of the supporting member. As a result, simply transferring the calculated end reaction may not accurately represent the actual load path or produce an appropriate design. Rather than risk giving the impression that these effects have been accounted for when they have not, the concrete and masonry beam modules currently require these loads to be entered manually. This allows the engineer to determine the appropriate loading based on the framing conditions and detailing of the structure. We understand that automatic load transfer for concrete and masonry would be a useful workflow improvement, and it is something we may revisit in the future if we can implement it in a way that accurately reflects the underlying engineering assumptions. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.enercalc.com/sel-faq/using-the-software/calculation-modules/linked-loads/linked-loads-for-concrete-and-masonry.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
